IMPBOVED I tOCKiXGAVATOR.

1'0 ALL WHOM IT MY CONGERN:

-:Be it known that I, Win11. ELLIOT, of the city, countypand State of New York; have invented-new and improved Machinery for Excavating Rock and Ore; andI do hereby declare that the following is a full and e'zact description thereof, reference being hnd to the accompanying drawings, and tothe letters of reference mark'ed thereon.

Similar letters of referen'ceindicate thc'same devices in all the figures.

To enable others skilled in the arts tocomprehe'nd, make, and use my invention,- will' proceed to describe its nature, construction, and operai-ion. i

The nature of`my invention consists ih suspending from a car, which is provided' with wheels which run upon tracksor ways nearA or above-,the surface of the earth, a drilling machine for drilling rocks, ores; and such like substances, and also in suspending a. platform for the support of a drilling machine, pulleys, belts, &c., the whole being suspended by iron rods, wire, ropes, or other adjustable supports, the power for driving the drilling machine being derived from a steam engine onthe car, whichis so employed as to drive the' car along upon the track, or to drive the machinery suspended under it; in providing proper braces for the platform and machinery, to hold them in a iixedposition while the machinery is running# in providing suitable`- stops for the car, to prev'ent it from moving; and in conveying the power of [the engine from thecar to the platform, or the drilling machines-thereon, by means of belts-and pulleys, conductingfpipes, or other suitsble'devices..

A. round belt .is employed here, so that'th'e varying positionso'f the drilling machine shall not derange it. Pulleys 1n and l are supported on the top of swinging frame m, which has its hinge around shaft sv, and is caused, by a spring `or weight, to swing from the drilling machine, so irs to kccp its belt always tightV and accommodate its movements. n, crank of the drilling machine. n', connecting-rods. o, braces en the platform, which rest against the rock. o', brace between the c ar and the platform. p, stop, which is fastened at its lower end to the track, and hinged at its upper end to the car, for holding the car stationary. 'Y q, gear on one of the axlesof the car. g', pinion meshing into gear q. r, tight and loose pulleys on the same shaft with pinion l51.. .1, belt connecting pulleys 1' with the engine. 1', drill attached to the drilling machine. V

Steam engines and rock-drilling `machines are so well known that it is not .necessary for the purposes of this application that they should be shown or specied in detail.v Almost any of the portable engines-now in use may be employed for this purpose, and any' practical rock-drill majr be used, whether propelled by belts, compressed air, or by steam. i

My invention refersy to the liandling,applying, and working of any rock-drillin deep rock cutting, mines, 85e.

Figs. 1 and 2 show the application of my invention to sewer'si These are usually cut from fourv to six feetl wide, and from ten tn eighteen feet deep. The two tracks h are first laid down on the streeLSat a. proper dis tance from each other, andthe earth .removed between them where the sewer is to be made. The car, with its suspended machinery, is then rnn upon the track and passed over its entirelength, drilling, as it comes to them, the higher points of the rock for blasting. The machine is then lowered two or three feet and passed over the length of 'the serrer again, drilling all the rock within its reach, and so on, lowering the bottom of the sewer two or three feet eaehtinie the machine passes over it. When itis necessary to move .the car from one place 'to another `on the track, the Stopp is detached from the track, the belt r run on to the tight pulley, when the car will move slowly o'.. Having moved far enough to bring the drills to a properpoint for other holes, the car is stopped, the Stopp fastened' to the track, the braces o run out against the sides cf the cut,-the machine lowered tothe rock andstarted up. The platform `for narrow sewers should have one machine upon it at each end ;v for wide sewers'it should have two machines at each end. The swinging frame maybe placed upon the carin a horizontal position, with pull'cy m over m. This would accommodate the motions of the drilling machine, .and allow the platform to be raisedhigh enough to drill upon the surface. Following this car at a proper.dis tance there should be another car, propelled by an engine carrying n. steam crane, and a shield, composed of timber-bolted together, so that when several holes have been charged the car may be caused tocarry theshield over them to confine the dying fragments of rock when the explosion takes place. 'After blasting, the steam crane may be used` to raise the detached rock;

Fig. 3 shows the application of mylinvention to deep vertical mines. The drilling machines at the bottom lof the mine are driven from the y-wheel of the engineby a system of belts and pulleys reaching from one` vplatform to another from the top to thc-bottom of the mine. The director of the work wo'uld'ind it necessary to remain at the bottom of the mine, and to enable him to operate the engine for driving or moving the machinery, there should be a system of levers and conneetingu'ods'reaching from the lower platform to the engin'e. To communicate his wishes to the rcman there should be a speaking-tube and Iabell both at top and bottom, with the necessary bell wires. There should also be a stairway or hoisting apparatus, for the use of laborers. In addition to these appliances, there should be a .force-pump for draining the mine and for producing asmall powerful stream'of water for washing chip out of drill holes. There should also be attached to the car a fan-blower for Ventilating the mine, and a gas apparatus, with gas pipes descending to the bottom of the mine, for lighting it. The drilling machinery for mines, like that vfor sewers, should be made to travel the entire length of, the mine, drilling rows of holes across the mine at proper distances,vand moving along by the locomotive power of the engine, as occasionrequires. 'Following this-at a convenient distance, the blasting and elevating machinery would do its work, the whole travelling over the mine from-one end tothe other, reducing the bottom about three or four feet each time it passes along. -The adjustable supports reaching from the lower platfdrm to the first one above it should be of wire rope wound upon. windlasses, so that the machines may be lowered conveniently asl the mine deepens. It may be necessary. in some cases to place the steam engine on the- 'suspended platform, but in most cases it will need to be'on the car.

Fig, 5 shows the application of my invention to the excavation of canals and cellars, and all rock-cutting of similar character. This diEers from the other principally in the employment of a sub-car, d, which stretches across' the excavation, carrying the cara, with its engine, suspended platform, and machinery. Sub-card moveslongitudinally over the excavation, while the car itsupports. moves across it, to bring the drills' to any required point. The steam engine should be so connect d with the sub-car as to cause itto move upon its tracks as well as with the car a, to` cause it to move upon its tracks L.
